ATTACHMENT FOR LEVELING BlLLlARD-TABLES.

SPECIFICATION forming part of Letters Patent No. 331,297, dated December 1, 1885.

Application filed October 4, 1884.

To all whom it may concern:

Be it known that I, OHARLEs B. HALL, a citizen of the United States, residing at the city, county, and State of New York, have invented a new and useful Improvement in Attachments for Leveling Billiard-Tables, of which the following is a specification, reference being. had to the accompanying drawings, forming a part of the same, in which Figure l is a side elevation; Fig. 2, a similar view,partly in section; and Fig. 3, acrosssection at d, Fig. 2, of a device embodying my invention.

Similar letters of reference indicate corresponding parts in the several figures.

The object of my invention is to facilitate the adjustment of the level of the bed of billiard-tables, and, further, to render such adjustment accurate by means of a simple and convenient device attached to the end of each leg as a permanent fixture that supports said bed; and in order that others may understand and use my invention, I will first proceed to describe the construction and relative arrangement of its respective parts, to explain its operation, and subsequently point out in the claim its novel characteristics.

In the drawings,a represents the lower end of a leg of a billiard-table with my invention attached. (Shown inside elevation,Fig. 1, and partly in section, Fig. 2.) The leg at is bored at the base, as shown at b, to receive a sleeve or bushing, d, composed of metal, (as are also the remaining parts of the device,) and constructed with one or more projecting wings 0r feathers, d, that enter corresponding grooves in the leg at, and a circumferential base-flange that retains it in place, the former preventing its rotation and the latter forming a shoulder surrounding the cavity 1), and also a bearing for the adj usting-nut h. This sleeveis intended' as a fixed bushing, and may be cemented in place or secured in any other suitable manner.

0 is a spindle, made with a smooth cylindrical surface for about one-half its length, that is closely fitted within the sleeve (l to allow the latter to slide vertically thereon, the remaining portion of its length being reduced indiameter and provided with a screw-thread, The end of the threaded portion of the spindle cis fast- Serin-l No. 144,755. (No model.)

ened to a foot-piece, k, shown in the form of a disk, that .rests upon the floor of the room, and provided with base projecting points k to hold it in place.

The spindle c and its foot-base k compose the stationary parts of the device, the base being made removable to allow the adjustingnnt h to be removed or replaced.

Each screw-thread and its adjusting nut should be of sufficient size to sustain its portion of the distributed weight, and also be made of low pitch to insure a slight vertical adjustment.

The adj usting-nut h shown is constructed in the form of a circular disk that may be operated directly by the hand or by placing a small lever or other convenient tool horizontally Within the recesses m made in its periphery.

In connecting the device, the spindle a should be inserted a sufficient distance within the sleeve d to cover a part of the threaded por" tion, as shown, for example, in Fig. 2, in order that the base-flange of the sleeve d and the adjusting-nut h may be in contact within a reasonable range of the vertical movement necessary for adjustment.

In the operation of the device,which will be readily understood from the foregoing description and inspection of the drawings, it will be observed that the extended vertical bearingsurface of the spindle 0 within the sleeve and the comparative horizontal surface of the nut upon its base-flange insure great steadiness of adjustment and a practical avoidance of lost motion in the operative parts.

Having thus fully described my invention, what I claim, and desire to securejby Letters Patent, is-- A leveling attachment for billiard-tables, consisting of a sleeve or bushing inserted and secured within and at the end of the legfa spindle fitted within said sleeve, and having its extended portion reduced and threaded, a base or removable foot-piece connected to the threaded end of said spindle, and a nut for adjusting the leg and fixed sleeve vertically upon the spindle, substantially as described.

CHARLES E. HALL.
